Interplanetary scintillation observations of the flat spectrum radio sources at 102.5 MHz.

From interplanetary scintillation observations of a sample of the flat-spectrum radio sources at 102.5 MHz, the author has obtained the flux densities, angular sizes of the scintillating components and compactness parameters. The comparison of these observations with the 327 MHz observations of the sample and with the computed distribution of compactness parameters has shown that flat-spectrum radio sources are still very compact at the wavelength of 3 m.
